Netflix has not confirmed or denied the reports, and they do not take into account mobile viewing, but it appears Stranger Things is on par with television's highest-rated shows.

The report reveals that the tweets about the "Stranger Things" season 2 premiere were far greater in number than the tweets about two of Netflix's popular shows, such as "House of Cards", which received only 54,458 mentions on Twitter, and "Orange is the New Black", which received only 105,753 mentions within two days of their premieres. All measure viewership over the first three days.

Approximately 11 million viewers the overall Live + 3 Day total were part of the adults 18-49 demographic with 361,000 people tuning in for all nine episodes of the sequel season on the first day of release.

The Nielsen ratings also don't measure viewership outside the U.S., even though most of Netflix's original series are released globally and more than half of it subscribers live in an worldwide market. Since its release on October 27, that number has bounced up to at least 4 million US viewers.

"The data that Nielsen is reporting is not accurate, not even close, and does not reflect the viewing of these shows on Netflix", the company said in a statement at the time of the original announcement.
